Artificial Intelligence Can Tell If You're Lying

One of the most powerful aspects of artificial intelligence is that it can see things that humans can’t.

More precisely, it can analyze data and find previously unseen correlations, some likely never to be discovered manually on a recurring basis.

Now researchers are tapping AI to tell if a person is lying, such as in a courtroom trial.

The system for covert automated deception detection, named DARE (Deception Analysis Reasoning Engine), is an AI engine that uses video features that detect human micro-expressions.

Researchers from the University of Maryland and Dartmouth College used real-life courtroom trial videos. Their system used classifiers trained on video features that predict human micro-expressions, which they determined could be used to predict deception.

The researchers created a three-step process involving capturing audio and video and then data encoding.

They trained their AI engine to identify the five most predictive micro-expressions: frowning, eyebrows raising, lip corners up, lips protruded and head side turn.

The researchers created a database of trial video clips, with 50 truthful videos and 54 that were deceptive.

They then had 15 people watch the videos and the DARE system ended up being more accurate than the people in predicting when someone in the video was lying.

The AI engine detected deception at a rate of 92%.

Artificial intelligence can combine audio, video and transcriptions in real-time to make a determination. It can see and process more things simultaneously and conclude which statements are likely not true, with a high degree of accuracy.

In the future, it may be difficult to lie to AI.

    Sounds terrible. What if you're telling the truth, and the machine insists you're lying? The jury might be inclined to believe the machine, and then you're convicted of a crime you never committed. All from the testimony of a bot! I'll pass.

    It is quite a distance from being used for that, Carl, but good points.
